Abstract
A wireless device capable of wireless local area network (WLAN) communications and cellular network communications stores profiles of wireless local area networks. The device identifies in which cell of a cellular network the device is currently located, and then scans more frequently for wireless local area networks matching profiles to which, previously, the device has connected while located in the cell, than for wireless local area networks matching other profiles.
Claims15
A method in a device capable of wireless local area network (WLAN) communications and wireless wide area network communications, the method comprising:
- storing profiles of wireless local area networks;
- identifying in which cell of a cellular network the device is currently located;
- and
- scanning more frequently for wireless local area networks matching profiles to which, previously, the device has connected while located in the cell, than for wireless local area networks matching other profiles.
A wireless device comprising:
- a processor;
- a wireless local area network (WLAN) interface coupled to the processor;
- a wireless wide area network interface coupled to the processor;
- and
- a memory coupled to the processor, the memory to store profiles of wireless local area networks and to store code which, when executed by the processor, identifies in which cell of a cellular network the device is currently located and causes the WLAN interface to scan more frequently for wireless local area networks matching profiles to which, previously, the device has connected while located in the cell, than for wireless local area networks matching other profiles.
A computer readable medium storing instructions which, when executed by a processor of a wireless device having a wireless local area network (WLAN) interface and a wireless wide area network interface, result in the device identifying in which cell of a cellular network the device is currently located and causing the WLAN interface to scan more frequently for wireless local area networks matching profiles to which, previously, the device has connected while located in the cell, than for wireless local area networks matching other profiles.
